I have 4 shipping options on my store,
local (within my city)
rest of new Zealand urban
rest of New Zealand Rural
and free shipping over $150
When people check out it automatically selects their shipping price based on their address, but 9 times out of 10 it is wrong.
For instance yesterday all my sales were only charged for local delivery even though most of them were not local and some were not local and rural so im taking big hits on the cost of shipping.
How do i fix this please?
